Discussion ´ ´ The Direction Generale de l’Aviation Civile (DGAC), which is the airworthiness authority for France, notified us that an unsafe condition may exist on certain Airbus Model A319, A320, and A321 airplanes. The DGAC advises that, during deployment tests of slide rafts at the forward passenger doors, cases of girt bar disengagement from the floor fitting were reported. Investigations have demonstrated that the girt bar disengagements were due to incorrect position of the stiff part of the girt bar during installation of the slide raft on airplanes. This may cause inboard-directed loads on the girt bar, preventing a correct engagement in the floor fittings. This condition, if not corrected, could result in disengagement of the telescopic girt bar from the airplane when the door is opened in emergency situations, which could result in the inability to open the passenger door and to use the escape slide/raft at that door during an emergency evacuation of the airplane. Relevant Service Information Airbus has issued Service Bulletin A320–25–1394, Revision 01, dated December 12, 2005. The service bulletin describes procedures for a general visual inspection to determine whether the stiff part of the girt and girt bar position of the forward left-hand and right-hand passenger doors is incorrect, and repair if necessary. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. The DGAC mandated the service information and issued French airworthiness directive F–2005– E:\FR\FM\12JNP1.SGM 12JNP1 33662 Federal Register / Vol. 71, No. 112 / Monday, June 12, 2006 / Proposed Rules 172 on December 21, 2005, to ensure the continued airworthiness of these airplanes in France. FAA’s Determination and Requirements of the Proposed AD These airplane models are manufactured in France and are type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Pursuant to this bilateral airworthiness agreement, the DGAC has kept the FAA informed of the situation described above. We have examined the DGAC’s findings, evaluated all pertinent information, and determined that we need to issue an AD for airplanes of this type design that are certificated for operation in the United States. Therefore, we are proposing this AD, which would require accomplishing the actions specified in the service information described previously. Costs of Compliance This proposed AD would affect about 719 airplanes of U.S. registry. The proposed actions would take about 1 work hour per airplane, at an average labor rate of $80 per work hour. Based on these figures, the estimated cost of the proposed AD for U.S. operators is $57,520, or $80 per airplane. wwhite on PROD1PC61 with PROPOSALS Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, Section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the Agency’s authority. We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701, ‘‘General requirements.’’ Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings We have determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a substantial direct effect on the States, on the relationship between the VerDate Aug<31>2005 20:57 Jun 09, 2006 Jkt 208001 national Government and the States, or on the distribution of power and responsibilities among the various levels of government. For the reasons discussed above, I certify that the proposed regulation: 1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866; 2. Is not a ‘‘significant rule’’ under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and 3. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation. deployment tests of slide rafts at the forward passenger doors. We are issuing this AD to prevent disengagement of the telescopic girt bar from the airplane when the door is opened in emergency situations, which could result in the inability to open the passenger door and to use the escape slide/raft at that door during an emergency evacuation of the airplane. Compliance (e) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. Inspection and Repair Comments Due Date (a) The FAA must receive comments on this AD action by July 12, 2006. (f) Within 200 days after the effective date of this AD, do a general visual inspection to determine if the stiff part of the girt and girt bar position of the forward left-hand and right-hand passenger doors is incorrect, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320– 25–1394, Revision 01, dated December 12, 2005. If the stiff part of the girt or the girt bar position is incorrect, before further flight, repair in accordance with the service bulletin. Note 1: For the purposes of this AD, a general visual inspection is: ‘‘A visual examination of an interior or exterior area, installation, or assembly to detect obvious damage, failure, or irregularity. This level of inspection is made from within touching distance unless otherwise specified. A mirror may be necessary to ensure visual access to all surfaces in the inspection area. This level of inspection is made under normally available lighting conditions such as daylight, hangar lighting, flashlight, or droplight and may require removal or opening of access panels or doors. Stands, ladders, or platforms may be required to gain proximity to the area being checked.’’ (g) Inspecting and repairing if necessary before the effective date of this AD in accordance with Airbus Service Bulletin A320–25–1394, dated July 23, 2004, is acceptable for compliance with the requirements of paragraph (f) of this AD. Affected ADs (b) None. Alternative Methods of Compliance (AMOCs) Applicability (c) This AD applies to Airbus Model A319, A320, and A321 airplanes, certificated in any category; on which Airbus Modification 20233, 25902, or 24365 (installation of slide raft) has been done in production; excluding those airplanes having manufacturer’s serial numbers 1794, 2155, 2195, 2204, 2231, 2239, 2244, 2246, 2247, 2252, 2254, 2255, 2257, 2259, 2261, 2263, 2267, 2273, 2274, 2275, 2278, 2280, 2282, 2284, 2286, 2288, 2297, 2301, 2307, 2310, 2314, 2327, 2369, and subsequent. (h)(1) The Manager, International Branch, ANM–116, Transport Airplane Directorate, FAA, has the authority to approve AMOCs for this AD, if requested in accordance with the procedures found in 14 CFR 39.19. (2) Before using any AMOC approved in accordance with § 39.19 on any airplane to which the AMOC applies, notify the appropriate principal inspector in the FAA Flight Standards Certificate Holding District Office.

This proposed AD would require replacing the clamp bases for the fuel vent pipe with improved clamp bases. This proposed AD results from reports that the foil wrapping on existing plastic clamp bases has migrated out of position, which compromises the bonding of the fuel vent pipes to the airplane structure. We are proposing this AD to ensure that the fuel vent pipes are properly bonded to the airplane structure. Improper bonding could prevent electrical energy from a lightning strike from dissipating to the airplane structure, and create an ignition source, which could result in a fuel tank explosion.

Comments will be available in the AD docket shortly after the Docket Management System receives them. Discussion The FAA has examined the underlying safety issues involved in fuel tank explosions on several large transport airplanes, including the adequacy of existing regulations, the service history of airplanes subject to those regulations, and existing maintenance practices for fuel tank systems. As a result of those findings, we issued a regulation titled ‘‘Transport Airplane Fuel Tank System Design Review, Flammability Reduction and Maintenance and Inspection Requirements’’ (67 FR 23086, May 7, 2001). In addition to new airworthiness standards for transport airplanes and new maintenance requirements, this rule included Special Federal Aviation Regulation No. 88 (‘‘SFAR 88,’’ Amendment 21–78, and subsequent Amendments 21–82 and 21–83). Among other actions, SFAR 88 requires certain type design (i.e., type certificate (TC) and supplemental type certificate (STC)) holders to substantiate that their fuel tank systems can prevent ignition sources in the fuel tanks. This requirement applies to type design holders for large turbine-powered transport airplanes and for subsequent modifications to those airplanes. It requires them to perform design reviews and to develop design changes and maintenance procedures if their designs do not meet the new fuel tank safety standards. As explained in the preamble to the rule, we intended to adopt airworthiness directives to mandate any changes found necessary to address unsafe conditions identified as a result of these reviews. In evaluating these design reviews, we have established four criteria intended to define the unsafe conditions associated with fuel tank systems that require corrective actions. The percentage of operating time during which fuel tanks are exposed to flammable conditions is one of these criteria. The other three criteria address the failure types under evaluation: single failures, single failures in combination with a latent condition(s), and in-service failure experience. For all four criteria, the evaluations included consideration of previous actions taken that may mitigate the need for further action. We have determined that the actions identified in this AD are necessary to reduce the potential of ignition sources inside fuel tanks, which, in combination E:\FR\FM\12JNP1.SGM 12JNP1

Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Airbus Model A319, A320, and A321 airplanes. This proposed 
AD would require an inspection to determine if the stiff part of the 
girt and girt bar position of the forward left-hand and right-hand 
passenger doors is incorrect, and repair if necessary. This proposed AD 
results from cases of girt bar disengagement from the floor fitting 
during deployment tests of slide rafts at the forward passenger doors. 
We are proposing this AD to prevent disengagement of the telescopic 
girt bar from the airplane when the door is opened in emergency 
situations, which could result in the inability to open the passenger 
door and to use the escape slide/raft at that door during an emergency 
evacuation of the airplane.

Discussion

    The Direction G[eacute]n[eacute]rale de l'Aviation Civile (DGAC), 
which is the airworthiness authority for France, notified us that an 
unsafe condition may exist on certain Airbus Model A319, A320, and A321 
airplanes. The DGAC advises that, during deployment tests of slide 
rafts at the forward passenger doors, cases of girt bar disengagement 
from the floor fitting were reported. Investigations have demonstrated 
that the girt bar disengagements were due to incorrect position of the 
stiff part of the girt bar during installation of the slide raft on 
airplanes. This may cause inboard-directed loads on the girt bar, 
preventing a correct engagement in the floor fittings. This condition, 
if not corrected, could result in disengagement of the telescopic girt 
bar from the airplane when the door is opened in emergency situations, 
which could result in the inability to open the passenger door and to 
use the escape slide/raft at that door during an emergency evacuation 
of the airplane.

Relevant Service Information

    Airbus has issued Service Bulletin A320-25-1394, Revision 01, dated 
December 12, 2005. The service bulletin describes procedures for a 
general visual inspection to determine whether the stiff part of the 
girt and girt bar position of the forward left-hand and right-hand 
passenger doors is incorrect, and repair if necessary. Accomplishing 
the actions specified in the service information is intended to 
adequately address the unsafe condition. The DGAC mandated the service 
information and issued French airworthiness directive F-2005-

[[Page 33662]]

172 on December 21, 2005, to ensure the continued airworthiness of 
these airplanes in France.

FAA's Determination and Requirements of the Proposed AD

    These airplane models are manufactured in France and are type 
certificated for operation in the United States under the provisions of 
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and 
the applicable bilateral airworthiness agreement. Pursuant to this 
bilateral airworthiness agreement, the DGAC has kept the FAA informed 
of the situation described above. We have examined the DGAC's findings, 
evaluated all pertinent information, and determined that we need to 
issue an AD for airplanes of this type design that are certificated for 
operation in the United States.
    Therefore, we are proposing this AD, which would require 
accomplishing the actions specified in the service information 
described previously.

Costs of Compliance

    This proposed AD would affect about 719 airplanes of U.S. registry. 
The proposed actions would take about 1 work hour per airplane, at an 
average labor rate of $80 per work hour. Based on these figures, the 
estimated cost of the proposed AD for U.S. operators is $57,520, or $80 
per airplane.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, Section 106, describes the 
authority of the FAA Administrator. Subtitle VII, Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701, ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We have determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would not 
have a substantial direct effect on the States, on the relationship 
between the national Government and the States, or on the distribution 
of power and responsibilities among the various levels of government.
    For the reasons discussed above, I certify that the proposed 
regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979); and
    3. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket. See the 
ADDRESSES section for a location to examine the regulatory evaluation.

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

    2. The Federal Aviation Administration (FAA) amends Sec.  39.13 by 
adding the following new airworthiness directive (AD):

Airbus: Docket No. FAA-2006-24990; Directorate Identifier 2006-NM-
013-AD.

Comments Due Date

    (a) The FAA must receive comments on this AD action by July 12, 
2006.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Airbus Model A319, A320, and A321 
airplanes, certificated in any category; on which Airbus 
Modification 20233, 25902, or 24365 (installation of slide raft) has 
been done in production; excluding those airplanes having 
manufacturer's serial numbers 1794, 2155, 2195, 2204, 2231, 2239, 
2244, 2246, 2247, 2252, 2254, 2255, 2257, 2259, 2261, 2263, 2267, 
2273, 2274, 2275, 2278, 2280, 2282, 2284, 2286, 2288, 2297, 2301, 
2307, 2310, 2314, 2327, 2369, and subsequent.

Unsafe Condition

    (d) This AD results from cases of girt bar disengagement from 
the floor fitting during deployment tests of slide rafts at the 
forward passenger doors. We are issuing this AD to prevent 
disengagement of the telescopic girt bar from the airplane when the 
door is opened in emergency situations, which could result in the 
inability to open the passenger door and to use the escape slide/
raft at that door during an emergency evacuation of the airplane.

Compliance

    (e) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

Inspection and Repair

    (f) Within 200 days after the effective date of this AD, do a 
general visual inspection to determine if the stiff part of the girt 
and girt bar position of the forward left-hand and right-hand 
passenger doors is incorrect, in accordance with the Accomplishment 
Instructions of Airbus Service Bulletin A320-25-1394, Revision 01, 
dated December 12, 2005. If the stiff part of the girt or the girt 
bar position is incorrect, before further flight, repair in 
accordance with the service bulletin.
    Note 1: For the purposes of this AD, a general visual inspection 
is: ``A visual examination of an interior or exterior area, 
installation, or assembly to detect obvious damage, failure, or 
irregularity. This level of inspection is made from within touching 
distance unless otherwise specified. A mirror may be necessary to 
ensure visual access to all surfaces in the inspection area. This 
level of inspection is made under normally available lighting 
conditions such as daylight, hangar lighting, flashlight, or 
droplight and may require removal or opening of access panels or 
doors. Stands, ladders, or platforms may be required to gain 
proximity to the area being checked.''
    (g) Inspecting and repairing if necessary before the effective 
date of this AD in accordance with Airbus Service Bulletin A320-25-
1394, dated July 23, 2004, is acceptable for compliance with the 
requirements of paragraph (f) of this AD.

Alternative Methods of Compliance (AMOCs)

    (h)(1) The Manager, International Branch, ANM-116, Transport 
Airplane Directorate, FAA, has the authority to approve AMOCs for 
this AD, if requested in accordance with the procedures found in 14 
CFR 39.19.
    (2) Before using any AMOC approved in accordance with Sec.  
39.19 on any airplane to which the AMOC applies, notify the 
appropriate principal inspector in the FAA Flight Standards 
Certificate Holding District Office.
